Yes, it's necessary if you're building your national strategy around carbon and soils, or trees for that matter, to put measures in place that make sure it will stay there. Otherwise, it will be re-emitted or it can be re-emitted. That's a critical concern that people are thinking about around the world with carbon sequestration and national plans.
Also, think about how you want to handle it if something happens that's outside of the farmer's control, like a fire or an extended multi-year drought, a shift to a drier climate, which will mean the loss of some of that soil carbon. These are important things to build in.
I don't particularly have the answers to how that might be done, but it would certainly be something to take into account, that it's somewhat vulnerable.
